Overload Measurement System Weight Watcher

    %>
  • Simple installation at the joint of the wire rope
  • %>
  • Transfer to relay signal control panel in case of overload of elevator
  • %>
  • HOLD function eliminates the need to compensate for changes in weight during the calibration chain or movement
  • %>
  • Up to 16 sensors can be connected
  • %>
  • Real-time load value can be checked and set by LCD of indicator
INTRODUCE소개
  • For each rope, sensors are mounted directly on the rope or in blind spots. The sensor is connected to the datalogger and instantly displays the total weight and individual rope loads without weight and calibration. The desired alarm is set on the display and on the device's keys or free PC software. The device provides alarms for up to four load thresholds, loose rope conditions, and a single released rope load.
